STOPEB FOB CLOSING THE CONTAINERS OF ELECTRIC ACCUM ULATORS.

. Application filed October 25, 1920, Serial No. 419,531. .Renewed March30,1923.

To all'whomz't may concern:

Be it known that I, FE-RNAND VAN DE VVIEL, a subject of the King ofBelgium, residing at Paris, France, have invented new and usefulImprovements in Stoppers for Closing the Containers of ElectricAccumulators, of which the following is aspecification.

The present invention relatcs'toimprovements relating to stoppers forclosing the containers of electric accumulators.

In electric accumulators of which the containers are provided with acover, a stopper which permits the'escape of the gas is necessary. 7

According to the present invention such stoppers are so constructed as.to provide the following combinati'onof features viz: that the gasescharged with liquid particles are constrained by one or more verticalbaffles to traverse a circuitous path between their entrance into thestopper and their escape into the surrounding air; and further the gasesenter and leave the stopper at points which are at a higher level thanthose through which liquid particles carried in suspension by the gasrespectively return to the vessel or re-enter the stopper.

In the accompanying drawing Figures 1 and 3 are sectional and planviews-respectively, of the improved stopper;

Figures 2 and 4 are sectional and .plan views, respectively, of amodification of the stopper;

Figures 5 and 6 are sectionaland plan views, respectively, of a furthermodification of the stopper.-

Referrin to Fi s. 1-4 the gases charged with 'liqui partic es enter thestopper by openings A where the battle 3 causes them to traverse acircuitous course during which they leave on the walls C, D, E, F theliquid particles with which they are charged.

These'particles collect in the bottom of the stopper and re-enter thecontalner through holes G, the presence .of the liquid in the passthrough openings L in t annular channel between the walls of the baflieand the stopper enter the latter by the open'm A, whence they escape bythe apertures the liquid particles collecting in the hollow I andreturning to the container by the opening J and the openings at thebottom of the stop' er.

ti le bafiles cou d be 0 the stopper.

Having now particularly described and It is obvious that mulplacedin'the interior ascertained. the nature of my said invention and in whatmanner the same is to be per.- formed, I declare that what I claim is:

A stopper for an electric accumulator comprising a body having gas inletports. a separate liquid outlet port at the bottom of the body arrangedat a lower level than the gas inlet ports, gas outlet'ports'at the upperpart of the body, a liquid inlet port located at a lower level than saidgas outlet ports, and bafliesinterposed between'the gasinlet ports andalso interposedbetween the gas and liquid outlet ports arranged to causethe outgoing gases to traverse a circuitous path,

said baflle being also arranged to intercept the direct fiow of gas fromthe liquid outlet port to the gas outlet port.

'In testimony whereof I have signed my name to this specification 1FERNAND VAN or: WIEL.
